Forecasters at the Joint Typhoon Warning Center noted "While the structure continues to improve, winds will lag slightly as the primary circulation catches up to the secondary circulation represented by convection. The environment remains favorable for continued intensification with warm sea surface temperatures, low vertical wind shear, and radial outflow."
On Aug. 30 at 11 a.m. EDT (1500 UTC), the eye of Typhoon Jebi was located near latitude 17.8 degrees north and longitude 146.2 degrees west. That's about 161 nautical miles north-northeast of Saipan.
